Dumbarton – Private Road Groundworks & Tarmac Surfacing
A private access road in Dumbarton, Scotland, completed with groundworks, edging kerbs, surface preparation and a hardcore base. Two machine-laid tarmac layers followed: a 60 mm-thick base course using 20 mm aggregate, then a 40 mm-thick surface course using 6 mm aggregate. The paired photographs show the prepared base before tarmac laying and the finished road between the kerbed edges.
